--- Comment #4 from Achim <Stromeko at nexgo dot de> ---
Looking at the code in objdump, it relies on bfd to return the line number
information in constant time. This is what _should_ be happening if the
debuginfo stash is actually working, but apparently it either doesn't for some
files or recreation of info not in the stash takes a really long time so that
O(1) becomes O(N) somehow for the line number lookup.
